Classic66vair asked for my Monsoon review. I PM'd him but thought I would share...
Me said:Will it rattle the paint off of the car next to you at a stoplight? No. Does it provide plenty of volume to clearly here and enjoy every bit of a song while at 70mph with the top down? Easily!
I'm a bit of an audiophile, if that helps. I'm a musician with very picky ears when it comes to sound (I spent 2 hours finding the correct angle for my floor speakers in my home theater ) and I'm very happy with the tone and crispness of the sound throughout the volume range. The bass from the sub-woofer fills out the sound nicely. Like I said before, 70mph is no problem. I can easily have the volume loud enough to mask almost all the engine and wind noise at that speed without a hint of distortion.
